This sequence selects the VFU channel that you want to use. Eight different channels are
available. The parameter m represents the channel that you want to select.

This command specifies the distance between the current print head position and the position
where you want to print subsequent characters (relative position). The distance is in number of
dots and must be calculated using the following formula:
Current position distance = n
1
+ (n
2
x 256)
where n
2
is the integer result of the number of dots divided by 256 and the n
1
is the remainder.
The unit of the dots is 1/120 inch for Draft printing or 1/180 inch for Letter Quality. If the
distance is negative (Most Significant Bit of m
2
equal to 1), the print head will be moved to the
left of the current position by a number of dots equal to the complement on two of n
1
+ (n
2
x 256).
